Thanks! Prior to building it, I knew nothing about the moon's motion - and learned there was a lot more to it then I thought! I am trying to think of a different way to drive the Z axis to make it more realistic - the motor has to stop and reverse, and this is the opposite of what it should be doing.(i.e it speed does vary, but not in that manner).

Thanks for the feedback! As I mentioned in Step 1 "I know very little about astronomy".I thought I could show a eclipse by matching the size of the light beam (in the first video, the focused flashlight that comes on at the end) to the size of the moon. I thought that since the (weird) coincidence of the Sun being 400 times bigger than the moon, but 400 times further away, gives them the same apparent size - I could explain this during the demo. The ring of LEDs that can be seen in the background on the second video, I made the same as the size of the globe - to show phases of the moon - but the ping-pong ball is too translucent to make it obvious. I posted this as my prototype, and it is feedback like this that will help me complete it. Thanks!
